swift - 如何从 HTTPURLResponse 保存 Cookie

Question

我正在开发一个登录应用程序，成功登录响应返回 2 个 cookie 后，我想从 HTTPURLResponse 的 header 中获取这 2 个 cookie，但我不能(httpResponse 字段不包含 cookie)如何我可以找到并保存它们以备将来使用吗？谢谢你帮助我

我的部分代码:

let task = URLSession.shared.dataTask(with: request ) { data, response, error in


        if let httpResponse = response as? HTTPURLResponse, let fields = httpResponse.allHeaderFields as? [String : String] {

            let cookies = HTTPCookie.cookies(withResponseHeaderFields: fields, for: (response?.url!)!)

            for cookie in cookies {
                //print ("hi")
                var cookieProperties = [HTTPCookiePropertyKey: Any]()
                cookieProperties[HTTPCookiePropertyKey.name]    = cookie.name
                cookieProperties[HTTPCookiePropertyKey.value]   = cookie.value
                cookieProperties[HTTPCookiePropertyKey.domain]  = cookie.domain
                cookieProperties[HTTPCookiePropertyKey.path]    = cookie.path
                cookieProperties[HTTPCookiePropertyKey.version] = NSNumber(value: cookie.version)
                cookieProperties[HTTPCookiePropertyKey.expires] = cookie.expiresDate

                let newCookie = HTTPCookie(properties: cookieProperties)
                HTTPCookieStorage.shared.setCookie(newCookie!)
            }            }
    }
    task.resume()

URLCache.shared.removeAllCachedResponses()
URLCache.shared.diskCapacity = 0
URLCache.shared.memoryCapacity = 0

if let cookies = HTTPCookieStorage.shared.cookies { 
    for cookie in cookies {
        HTTPCookieStorage.shared.deleteCookie(cookie)
    }
}
